CARBURETER.

Specification of Letters Patent.

Application filed September 23, 1910. Serial Na 583,439.

To all whom it may concern."

Be it known that I, ARTHUR Hirrisnnr,

asubject of the King of England, and resi- England, have invented an Improved Car 'bureter for Internal-Combustion Engines,

of which the following is a specification.

. This invention relates to carburetors having multiple jets brought into or out of use progressively.

According to this invention, the jets are arranged in a circle so as to feed inward into a central vertical air-pipe and may be covered or uncovered in pairs arranged diametrically opposite to one another. This may be eifected by a rotating sleeve, with ports, or in any other convenient manner.

Inthe accompanying drawings; Figure l is a central vertical section showing the preferred method of carrying out this invention, and Fig. 2 is a transverse section on the line 2-2 of Fig. 1.

Like letters indicate like parts figures.

In. this construction, a hollow annular chamber A termed a jet ring is used, and this is supplied with petrolor the like from in both 3 any suitable source, as by the pipe B, a constant level being preferably maintained.

This jet ring has formed in its inner periphery small outlets C which constitute the jets proper. These are arranged in pairs diametrically opposite one another, and

there may be any suitable number, say eight. This jet ring is supported from the body of the carbureter so as to leave a concentric space D between it and'the body E. The bottom of this space is provided with a perforated diaphragm F and a rotating disk G,

which are adapted to act as a valve. By this means the amount of air passing behind Copies of this patent may be obtained for the jets along the passages H and remainlng uncarbureted can be varied to vary the [richness of the mixture. dent of Ston- Easton, Bath, Somersetshire, '1

Within the'jet ring A is arranged a rotating sleeve J actuated by the lever J which ring has ports K ofdifferent lengths in the same plane as the jets C. The ports in the rotating sleeve are so arranged that as the sleeve is moved the jets are opened up or closed in pairs. The arrangement of the ets concentric with the air passages provides-good carburization While the rotating sleeve enablesthe'ei'fectivesize of the fuel outlet to be easilyva-ried.

The carbureter may be water jacketed orheated in any usual manner. For instance there may be a concentric j acketL arranged above the jet ring and resting thereon, this. jacket being fed with water or hot gas.

Having fully described my invention, what I claim and desire to secure by Letters Patent is The herein described carburetor, comprising the combination with the carbureter-casing, of a hollow. ring A concentrically disposed within the said casing and being provided with a plurality of symmetrically arwitnesses ARTHUR HIPPISLEY.
